[0056] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0057] Reference is made below Figures 1 - 8 to describe the outdoor unit 100 and the air conditioning equipment according to the embodiments of the present invention.

[0058] Refer to Figures 1 - 8 , according to the outdoor unit 100 of the first aspect embodiment of the present invention, the outdoor unit 100 includes: an outdoor unit housing 1 and an outdoor heat exchanger 2, an outdoor fan, a compressor assembly 3 and an electric control box component 4 provided in the outdoor unit housing 1. A middle partition 11 is provided in the outdoor unit housing 1, and the middle partition 11 divides the space in the outdoor unit housing 1 into a fan cavity 12 and a compressor cavity 13 arranged in the left-right direction. The outdoor heat exchanger 2 and the outdoor fan are provided in the fan cavity 12, the compressor assembly 3 is provided in the compressor cavity 13, and at least part of the electric control box component 4 is located in the compressor cavity 13.

[0059] Among them, at least part of the electric control box component 4 being located in the compressor cavity 13 may include the following several situations: for example, part of the electric control box component 4 is located in the compressor cavity 13, and the other part of the electric control box is located in the fan cavity 12; for another example, the electric control box component 4 is entirely located in the compressor cavity 13.

[0060] An air inlet 14 and an air outlet 15 communicating with the fan cavity 12 are formed on the outdoor unit housing 1. During the operation of the outdoor fan, the outdoor fan can drive the air flow to enter the outdoor unit housing 1 from the air inlet 14, exchange heat with the outdoor heat exchanger 2, and then be discharged to the outside of the outdoor unit housing 1 through the air outlet 15 after heat exchange.

[0061] The compressor assembly 3 includes a compressor, and the compressor assembly 3 can play a role in compressing and driving the refrigerant in the refrigerant circulation circuit of the outdoor unit 100.

[0062] The electric control box component 4 includes an electric control module 42 and a heat dissipation plate 8. The electric control module 42 can be electrically connected to an outdoor fan, a compressor assembly 3, etc., and can be used to control the operation of components such as the outdoor fan and the compressor assembly 3. During the operation of the electric control module 42, a large amount of heat will be generated. The heat dissipation plate 8 is used to dissipate heat from the electric control module 42 to prevent the electric control module 42 from being damaged due to heat or affecting the normal operation of the outdoor unit 100. The heat dissipation plate 8 is thermally connected to the electric control module 42. The heat dissipation plate 8 has a cavity 84 inside, and a heat-conducting liquid is accommodated in the cavity 84. The specific heat capacity of the heat-conducting liquid is greater than the specific heat capacity of the heat dissipation plate 8. The greater the specific heat capacity, the stronger the heat absorption ability. The specific heat capacity of the heat-conducting liquid is greater than the specific heat capacity of the heat dissipation plate 8. Therefore, the heat absorption ability of the heat-conducting liquid is stronger than that of the heat dissipation plate 8. Forming a cavity 84 containing a heat-conducting liquid on the heat dissipation plate 8 is beneficial to improving the overall heat absorption ability of the heat dissipation plate 8, enabling the heat dissipation plate 8 to more quickly export the heat generated by the electric control module 42, thereby improving the heat dissipation effect of the heat dissipation plate 8 on the electric control module 42.

[0063] Optionally, the electric control box component 4 further includes a first bracket 91. The heat dissipation plate 8 is installed on the first bracket 91, and the first bracket 91 is installed on the electric control module 42.

[0064] Optionally, the cavity 84 can be a closed cavity 84.

[0065] For the outdoor unit 100 according to the embodiment of the present invention, by making the heat dissipation plate 8 have a cavity 84 and accommodating a heat-conducting liquid with a specific heat capacity greater than that of the heat dissipation plate 8 inside the cavity 84, the greater the specific heat capacity, the stronger the heat absorption ability. Therefore, the heat absorption ability of the heat-conducting liquid is greater than that of the heat dissipation plate 8. In this way, the heat-conducting liquid accommodated in the cavity 84 improves the overall heat absorption ability of the heat dissipation plate 8. The heat dissipation plate 8 can more quickly export the heat generated by the electric control module 42, thereby improving the heat dissipation efficiency and heat dissipation effect of the heat dissipation plate 8 on the electric control module 42. Furthermore, it can reduce or avoid the adverse effects on the working ability of the outdoor unit 100 caused by the electric control module 42 being in a high-temperature working condition, and reduce or avoid the adverse effects on the air-conditioning ability of the air-conditioning equipment.

[0066] According to some embodiments of the present invention, the heat-conducting liquid is water. By making the heat-conducting liquid water, water is a substance with a relatively large specific heat capacity among common liquids, and water has good heat absorption ability, thereby enabling the overall heat absorption ability of the heat dissipation plate 8 to be effectively improved; in addition, the cost of water is relatively low.

[0067] According to some embodiments of the present invention, the density of the heat-conducting liquid is less than the density of the heat dissipation plate 8. By making the density of the heat-conducting liquid less than the density of the heat dissipation plate 8, the weight of the heat-conducting volume under the same volume is smaller, which is beneficial to reducing the weight of the heat dissipation plate 8, and further beneficial to the light weight of the outdoor unit 100.

[0068] Reference Figures 1 - 8 According to some embodiments of the present utility model, the outdoor unit 100 further includes a heat dissipation pipe 7. A heat dissipation flow channel for the flow of a heat exchange medium is provided inside the heat dissipation pipe 7, and the heat dissipation pipe 7 is thermally connected to the electronic control module 42. Optionally, the heat exchange medium flowing inside the heat dissipation pipe 7 may be a refrigerant. By providing the heat dissipation pipe 7 and thermally connecting the heat dissipation pipe 7 to the electronic control module 42, the heat dissipation pipe 7 can further improve the heat dissipation effect on the electronic control module 42.

[0069] According to some alternative embodiments of the present utility model, the specific heat capacity of the heat-conducting liquid is greater than that of the heat exchange medium. By making the specific heat capacity of the heat-conducting liquid greater than that of the heat exchange medium, the heat-conducting liquid has good heat-conducting ability to effectively dissipate heat from the electronic control module 42.

[0070] Reference Figures 3 - 8 According to some alternative embodiments of the present utility model, the heat dissipation pipe 7 is thermally connected to the heat dissipation plate 8. By thermally connecting the heat dissipation pipe 7 to the heat dissipation plate 8, it is convenient for the heat dissipation pipe 7 to timely export the heat on the heat dissipation plate 8, so as to achieve effective heat dissipation of the electronic control module 42.

[0071] Reference Figures 6 - 8 According to some alternative embodiments of the present utility model, the cavity 84 extends along the length direction of the heat dissipation plate 8 and is located in the middle of the width direction of the heat dissipation plate 8. At least a part of the heat dissipation pipe 7 surrounds the outer peripheral side of the cavity 84. The layout of the heat dissipation pipe 7 and the cavity 84 is reasonable, and such an arrangement makes the heat exchange area between the heat-conducting liquid in the cavity 84, the heat dissipation pipe 7 and the electronic control module 42 relatively large, making full use of the space on the heat dissipation plate 8; and the heat-conducting liquid in the cavity 84 can uniformly dissipate heat from the electronic control module 42, and the heat dissipation pipe 7 can further dissipate heat from the heat-conducting liquid in the cavity 84, both of which are beneficial to improving the heat dissipation effect on the electronic control module 42.

[0072] Reference Figures 3 - 8 According to some alternative embodiments of the present utility model, at least a part of the heat dissipation pipe 7 defines a U-shaped region, and the cavity 84 is located within the U-shaped region. Among them, at least a part of the heat dissipation pipe 7 defining a U-shaped region may include the following several situations: for example, a part of the heat dissipation pipe 7 defines a U-shaped region; for another example, the whole of the heat dissipation pipe 7 defines a U-shaped region. By making at least a part of the heat dissipation pipe 7 define a U-shaped region and the cavity 84 be located within the U-shaped region, the heat dissipation pipe 7 and the cavity 84 make full use of the space on the heat dissipation plate 8, and the structural arrangement of the heat dissipation plate 8 and the cavity 84 is compact.

[0073] Reference Figures 3 - 8, according to some alternative embodiments of the present utility model, the heat dissipation plate 8 includes a first heat dissipation plate 81 and a second heat dissipation plate 82 connected up and down. A receiving hole 83 is defined between the first heat dissipation plate 81 and the second heat dissipation plate 82, and at least a part of the heat dissipation pipe 7 is received in the receiving hole 83. For example, a part of the heat dissipation pipe 7 is received in the receiving hole 83; for example, the entire heat dissipation pipe 7 is received in the receiving hole 83. Such a setting is beneficial to improving the installation stability of the heat dissipation pipe 7, and is beneficial to full heat exchange between the heat dissipation plate 8 and the heat dissipation pipe 7, and further beneficial to further improving the heat dissipation effect on the electronic control module 42.

[0074] Optionally, the first heat dissipation plate 81 and the second heat dissipation plate 82 are detachably connected. For example, the first heat dissipation plate 81 and the second heat dissipation plate 82 are connected by fasteners.

[0075] According to some alternative embodiments of the present utility model, a heat conduction layer is provided between the heat dissipation pipe 7 and the inner wall of the receiving hole 83. By providing a heat conduction layer between the heat dissipation pipe 7 and the inner wall of the receiving hole 83, it is beneficial to improve the heat exchange effect between the heat dissipation pipe 7 and the heat dissipation plate 8, thereby improving the heat dissipation effect on the electronic control module 42. Optionally, the heat conduction layer is heat-conducting silicone grease.

[0076] Reference Figures 6 - 8 , according to some alternative embodiments of the present utility model, a cavity 84 is formed on the first heat dissipation plate 81 or a cavity 84 is formed on the second heat dissipation plate 82 or the first heat dissipation plate 81 and the second heat dissipation plate 82 jointly define a cavity 84. The setting method of the cavity 84 is flexible and can flexibly match the heat dissipation requirements of the electronic control module 42.

[0077] Optionally, cavities 84 may also be formed on both the first heat dissipation plate 81 and the second heat dissipation plate 82, and a heat-conducting liquid is received in the cavities 84.

[0078] Reference Figures 3 - 8 , according to some alternative embodiments of the present utility model, the first heat dissipation plate 81 and the second heat dissipation plate 82 are connected by fasteners, and the fasteners are spaced apart from the cavity 84. By connecting the first heat dissipation plate 81 and the second heat dissipation plate 82 by fasteners and spacing the fasteners from the cavity 84, it is avoided that the setting of the fasteners affects the airtightness of the cavity 84, and thus it is possible to avoid leakage of the heat-conducting liquid caused by the setting of the fasteners.

[0079] Reference Figures 1 - 2 , according to some alternative embodiments of the present utility model, a part of the pipeline of the refrigerant circulation system of the outdoor unit 100 constitutes the heat dissipation pipe 7. By making a part of the pipeline of the refrigerant circulation system of the outdoor unit 100 constitute the heat dissipation pipe 7, it is possible to effectively exchange heat between the heat dissipation pipe 7 and the electronic control module 42 by using the refrigerant as a heat exchange medium, and it is no longer necessary to separately provide a heat exchange pipe and a heat exchange medium.

[0080] ReferenceFigures 1 - 3 According to some alternative embodiments of the present utility model, the electronic control box component 4 further includes a box body 41, an electronic control module 42 and a heat dissipation plate 8 are arranged inside the box body 41. The box body 41 has an air inlet 411 and an air outlet 412. The air inlet 411 is communicated with the external space of the outdoor unit 100, and the air outlet 412 is communicated with the blower cavity 12. During the operation of the outdoor unit 100, the operation of the outdoor blower causes a pressure difference between the inside of the blower cavity 12 and the external space of the outdoor unit 100, so that the air flow in the external space can enter through the air inlet 411 of the box body 41 under the action of this pressure difference, and flow through the electronic control module 42 inside the box body 41 to fully exchange heat with the electronic control module 42 to realize the heat dissipation of the electronic control module 42. Then, the air flow can flow out of the box body 41 through the air outlet 412 and enter the blower cavity 12.

[0081] During the operation of the outdoor unit 100, the air flow temperature inside the outdoor unit housing 1 is relatively high. If the air flow inside the outdoor unit housing 1 is used to dissipate heat from the electronic control module 42 of the electronic control box component 4, the heat dissipation effect is poor. In this way, dissipating heat from the electronic control module 42 through the air flow in the external space of the outdoor unit housing 1 is beneficial to improving the heat dissipation effect, reducing or avoiding the electronic control box component 4 being in a high-temperature working condition, and reducing or avoiding the adverse impact on the operation of the outdoor unit 100 caused by the electronic control box component 4 being in a high-temperature working condition, and further reducing or avoiding the adverse impact on the air conditioning capacity of the air conditioning equipment.

[0082] For example, when the outdoor unit 100 is applied to a variable-frequency air conditioning equipment, dissipating heat from the electronic control module 42 through the air flow in the external space of the outdoor unit housing 1 to improve the heat dissipation effect can effectively avoid the outdoor unit 100 from self-limiting frequency protection due to the heat generation of the electronic control box component 4 under high-temperature working conditions, so that the air conditioning equipment can achieve a good air conditioning effect.

[0083] Reference Figures 1 - 3 According to some alternative embodiments of the present utility model, the outdoor unit housing 1 is formed with an air inlet 16. The air inlet 16 is located on the side wall of the compressor cavity 13, and the air inlet 16 communicates the air inlet 411 with the external space of the outdoor unit 100. By forming the air inlet 16 on the outdoor unit housing 1 to communicate the air inlet 411 and the external space, it is convenient for the air flow in the external space to smoothly enter the box body 41 through the air inlet 16; by making the air inlet 16 located on the side wall of the compressor cavity 13, the distance between the air inlet 16 and the blower cavity 12 is relatively far, which is beneficial to reducing the influence of the air flow flowing out of the blower cavity 12 on the temperature of the air flow at the air inlet 16, and is beneficial to the air flow entering the box body 41 through the air inlet 16 to effectively dissipate heat from the electronic control module 42.

[0084] Reference Figures 1 - 3, according to some alternative embodiments of the present utility model, an intake space 5 is defined between the electronic control box component 4 and the side wall of the compressor. The intake space 5 communicates the intake port 16 with the air flow inlet 411. By defining an intake space 5 that communicates the intake port 16 and the air flow inlet 411 between the electronic control box component 4 and the side wall of the compressor, the air flow can smoothly enter the box body 41 through the air flow inlet 411 to dissipate heat from the electronic control module 42.

[0085] During the operation of the outdoor unit 100, the operation of the outdoor fan causes a pressure difference between the inside of the fan chamber 12 and the external space of the outdoor unit 100. As a result, the air flow in the external space enters the outdoor unit housing 1 through the intake port 16 under the action of this pressure difference, then flows towards the air flow inlet 411 through the intake space 5 and can enter the box body 41 through the air flow inlet 411 of the box body 41, and flows through the electronic control module 42 in the box body 41 to fully exchange heat with the electronic control module 42 to achieve heat dissipation of the electronic control module 42. Then, the air flow can flow out of the box body 41 through the air flow outlet 412 and enter the fan chamber 12.

[0086] Reference Figures 1 - 3 , according to some alternative embodiments of the present utility model, in the left - right direction, the intake port 16 is located on the side of the compressor chamber 13 away from the fan chamber 12. By making the intake port 16 located on the side of the compressor chamber 13 away from the fan chamber 12 in the left - right direction, the distance between the intake port 16 and the fan chamber 12 is relatively far, which is beneficial to reducing the influence of the air flow flowing out of the fan chamber 12 on the temperature of the air flow at the intake port 16, and is beneficial to the effective heat dissipation of the electronic control module 42 by the air flow entering the box body 41 through the intake port 16.
